This test method is specifically directed at the spray painting of automobile car and light duty truck bodies. The general principles are applicable to the painting of other automotive parts.

This test method may also be used to measure transfer efficiency in full-sized painting facilities simulating production conditions and operations.

1.1 This test method covers procedures for determination of the transfer efficiency (using a weight method) under production conditions for in-plant spray application of automotive paints as outlined in Section 18 of EPA 450/3-88-018.

1.2 The transfer efficiency is calculated from the weight of the paint solids sprayed and that deposited on the painted part. The recommended approach involves painting the part directly. Also described is an alternative approach for painting parts covered with aluminum foil.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in 10.1.8.1.
